Engine speed and load requirements were determined from data supplied by Detroit Diesel Allison (DDA) for their 40 foot urban transit bus with Canadian DDA 6V71 NA (C55) engine. This information was in the form of a computer printout which listed engine speed, load, transmission gear, vehicle acceleration and position as a function of time. These data were fitted to the ADB cycle requirements at the Ontario Ministry of Transportation (MOT) in support of this program. A listing of the engine speed and torque versus time for all phases of the ADB cycle was provided of ORF where it was implemented on a computer-controlled engine dynamometer. The results of the test program indicate that alternative fuels have a useful role to play in reducing transit bus engine exhaust emissions.
